MECHANICAL-POWER BRAKE.

SPECIFICATION forming part of Letters Patent No. 786,378, dated April 4, 1905. Application filed January 23, 1904. Serial No. 190,300.

To all whom, it nuty concern:

Be it known that I, LoUIs PFINGST, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Mechanical-Power Brakes, of which the following is a specification.

My invention relates to new and useful improvements in hand or power driven brakespindles; and the object of my invention is to apply the brake mechanism of the car by power or hand.

My invention consists of certain novel features hereinafter described, and particularly pointed out in the claims.

In the accompanying drawings, which illustrate a construction embodying my invention, Figure 1 is a plan view of the bottom framing of the car and platform, showing the location of the motor and power-driven brakespindle with the usual arrangement of center brake-levers, truck, brakebeams, brakeshoes, and truck-brake levers on one end of the car.

Like letters of reference refer to like parts throughout the several views.

The bed-plate A is bolted to the platformbuffer timber a of the car, and secured to said bed-plate A by suitable bolts is the frame or support B. The bridging C is bolted to the lugs B, which are part of the base-frame or support B and forms, by means of the step M on the bridging C and the circular flange M, a bearing for the journal L of the hollow armature-shaft N, thereby su pporting the motor-armature N in its upright position, Fig. 3. Secured around the armature N are the pole-pieces O of usual construction and supported on and secured to the base-frame B. Secured to the upper ends of said pole-piece frame O is the extension motor-frame S, and to the upper end of said extension-frame is secured the upper bridging T to lugs U of said frame, and on the extreme upper end of said extension motor-frame S is a cap or covering Z, whose lower circular end Z is secured, by means of suitable bolts, to the extensionframe S. In the upper end of said cap Z is a suitable hearing A for the upper end of the spindle or shaft P. The bridging T has a central opening, which forms a bearing for the journal V on the upper end of the hollow armature-shaft N and also supporting brushholding brackets Y, on which are mounted suitable brushes Y. These brush-holding brackets are suitably insulated by insulating material Y from the upper bridging T. The electric current passes in through the in-wire B and is connected to the contact-plate B and when the circuit is closed, as hereinafter described, the current will pass, by means of the contact B, to the wire B' through the polefields of the motor, thence to the brushes Y,

passing through the armature, thence through the commutator O, thence through the opposite brush Y, thence out through the wire B as is usual.

Secured on the lower end of the journal L of the hollow armature-shaft N is the clutch member K, which rotates with the armature N and armature-shaft N. The other member, J, of the clutch is adapted to be raised to engage with the rotating upper member K, which will rotate the member J, which transmits its rotating motion through the aid of the spline or key I to the spindle P, as shown in Fig. 8, causing the rotation of said spindle P to wind up the chain Q. Thelower member J is raised by means of the clutch-lever 1 provided with a ring-lever E, pivoted at B to the loose cl utchring F. On opposite sides of said right lever I are two depending arms B, pivoted at B" to the links D, Fig. 9, which are also pivoted to the lugs B on the base-plate A, the arrangement of the arm B and links 1) forming a toggle- 'ioint, so that when the foot of the operator is placed on the lever E the arms B and links D move to a vertical line, raising the loose clutch-ring F in contact with the clutch member J, forcing it up to engage with the upper clutch member K and at the same time closing the circuit through the contactsprings B B' by means of the insulating metallic linger B, which comes in contact with both contact-springs B B" by this movement. Surrounding and attached to the spindle P is the ratchet-wheel G by means of the spline R to hold the spindle P when the brakes are set by means of the pawl H, which is moved by the foot of the operator to engage or disengage. This ratchet-wheel (Jr rests upon the circular boss R, which is part of the bed-plate A, as is also the boss R, which forms a bearing for the lower' end of the spindle P.

On the upper end of the spindle P there is arranged an oscillating clutch-handle A and its object is to allow the rotation of the spin dle P by electric-motor power without turning the handle A either when winding or unwinding the brake-chain Q. This is accomplished by disengaging the clutch-pin A from the orifices A, arranged at intervals around the upper end of the spindle, by lifting up the outer end of the handle A, which causes the handle to oscillate on the pivots A by means of the slot A". The collar A is the support for the handle A which is pivotally connected by the pins A and rotates with said handle; but when the handle is disengaged from the spindle the upper end of said spindle rotates within said collar A. Above and resting on said collar A is a washer A and above said collar is a pin A, driven into the upper end of the reduced spindle A' to hold the parts in place. The purpose of the handle is to rotate the spindle P when the power is not in operation. This is accomplished by allowing the clutch-pin A" to lit in the orifices A, that are located at intervals around the operating-spindle P. By this means the chain can be wound and the brakes set in a manner similar to that obtained when the current is on. During this operation without the use of the motor it is not necessary to engage the clutch members, as the spindle can be turned entirely by the handle without operating any of the motor mechanism. The same ratchetwheel Or can be used and hold the brakes whether the spindle is operated by the motor or by the handle.

As shown in Figs. 1 and 2, the platform construction consists of buffer-timber a, with a platform-flooring f. c is the supportingtimber fastened to the body of the car and supporting the flooring f and the buffer-timbers (1,. (Z is the bottom-frame cross-timber,

which is fastened to the side sill?) and is used for the purpose of supporting the car-liooring. is the end sill, which is fastened at the extreme end of the side sills 6, and to the end sills a the end frame of the car is secured in the usual manner of car-building. r is the main brake-rod, and at one end said rod is connected to the brake-chain Q, and the other end is pivotally connected to the center brakelever 71.. The main or center brake-lever 71 is supported by the bracket vi, secured to the bottom of the car, and has a loose motion in the slot and said brake-lever 71/ is held in place by the pin 70. Pivotally connected to the main brake-lever it is the secondary brakerod Z, pivoted at its opposite end to the truck brake-lever m, which is pivoted on the brakebeam 19. At the lower end of the brake-lever m is pivotally connected the brake rod 0, which at its opposite end is connected to the truck-adjusting arm a. On the ends of the brake-beam p is fastened the brake-shoes I], which come in contact with the periphery of the wheels 0', mounted on the axles s. The brake-rod g and the secondary brake-rod l (shown on the right of Figs. 1 and 2) extend forward and are connected to similar mcchan ism at the right-hand end of the ear.

The operation of this mechanism is as follows: By the rotating of the spindle P, winding up the chain Q, the brake-rod 1 will be pulled forward, actuating the brake-lever /t. This will pull in the opposite direction the secondary rod Z, and by this operation the secondary rod 6 will pull the truck-lever m toward the center of the car, pressing out the bottom end toward the end of the car, thereby causing the brake-beams p to travel in opposite directions and apply the brake-shoes to the wheels. By the arrangement of the spindle with the brake-handle, as hereinbefore described, the spindle can be revolved in either direction without rotating the handle, or the handle can be rotated in either direction without rotating the spindle or motor, or, if desired, the handle can rotate the spindle with the motor, or both can be operated at the same time. To operate the motor without the cur-.

rent, the clutch member J is raised up into engagement with the clutch member K by the lever E, so that by the rotation of the handle when in engagement with the spindle both the spindle and the motor can be rotated. The mode of operating the brake-spindle by power to set the brakes is as follows: First, start the motor running. Second, to apply the brake the operator puts pressure on the clutchlever E, bringing the clutch members I and K in contact with each other. This will rotate the spindle P. During this operation the operator holds by hand the loose or oscillating clutch-brake handle A disengaged from the spindle P. This will allow the rotating of the spindle P and the winding up of the chain Q, thereby pulling the brake-rod g, actuating the brake-lever lb, thence pulling the rods Z and actuating the truck-levers m, and thereby setting the brake. When the brake is sufiiciently set, the motor clutch members J and K are disengaged, thereby cutting out all motor-power, after which the brake is held when set either by the brake-handle A or the ratchet-wheel G and pawl H by engaging with the spindle P. To release the brake, the ratchet-wheel G and pawl are disengaged. During this operation the operator has hold of the brake-handle A Now to further complete the releasing of the brake the operator can disengage the pin A of the handle A from the orifices A on the spindle P, thereby permitting the spindle P to rotate in the other direction without rotating the handle A or motor-armature N by the brake-spring pull or chain Q and unwinding itself from the spindle P, or the operator might release the handle A allowing it to rotate with the spindle P. By either method the brake can be fully released. It does not follow that the motor must run continuously. It can be started to rotate before the clutch members J and K are engaged. When operating the clutch-lever E, the circuit can be closed by the linger B coming in contact with the plate 13*, thereby starting the flow of current to the motor, which will rotate said motor prior to the engagement of the clutch members J and K.
